Question

Given that at least one atm is working when the mall opens, would the expected value of the number of atms that are working be less than, equal to, or greater than the expected value from part (b)?

Answer 1

The comparison of the expected values cannot be made without additional information.

Step-by-step explanation:

To determine whether the expected value of the number of working ATMs when the mall opens is less than, equal to, or greater than the expected value from part (b), we need more information about the situation described in part (b). Without this information, it is not possible to compare the expected values of the two scenarios.
